With social media, email and texting at our disposal today, it’s hard not to get distracted by our smartphones. In 2016, the average American was reported to spend three hours and eight minutes a day on their smartphone, and that’s excluding voice activities such as phone or video calls.

There’s a number of other productive activities you could be doing with all that time. How about picking up a book? On average, a person spends a whopping 23 hours per month on social media on their phone. And all those hours you spent on Facebook and Instagram translates into a whopping five novels you could have read, including The Handmaid’s Tale, Jane Eyre, To Kill a Mockingbird and more.

If you’re not convinced, here’s an eye popping stat: With the average 118 hours a person spends a month with their smartphone on social media, instant and text messaging, email, photo and video messaging, phone and video calls monthly, they could have read 24 novels.
